FRITZ!Box 3390 Service - Knowledge Base

Updating FRITZ!OS manually

With the "Online Update" function you can install the latest FRITZ!OS for your FRITZ!Box quickly and easily. However, in some cases you cannot use the "online update" function, for instance when the FRITZ!Box is not connected to the Internet. In this case, you can manually update it.

1 Downloading the FRITZ!OS file

Use a computer with Internet access to download the update:

Note:If you cannot use your own FRITZ!Box to connect to the Internet, then you can download the latest FRITZ!OS at your neighbor's or in an Internet café, for example, and then copy it to a computer that is connected to your FRITZ!Box.
